Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.
How long has he been showing signs?
Any retching, gagging, lip licking, or vomiting?
Has he licked anything harmful? Any changes (ie sores, ulcers, redness, etc) in his mouth?
Is he drinking? Can he keep any water down?
Are his gums nice and pink (not white/pale)? Moist or sticky?
If you press on his belly, does he have any tensing, tenderness, discomfort, or pain?
